[0006] In view of the functional defects of the prior art, the object of the present invention is to provide a buried floor radiant cooling and heating air conditioning system, a control method and a central air conditioner to solve the problem of condensation on the floor surface of the current floor radiant air conditioner when it is used in summer. No problem, at the same time, it does not have the feeling of blowing, which improves the comfort of users. Each room is equipped with an independent temperature and humidity control system to meet the different needs of most people for cold and heat. The mode of peak shifting and valley filling is used to store cold and heat, with small investment. Reliable operation, suitable for different building types such as office buildings and industrial parks

specific Embodiment approach
[0054] The buried floor radiant cooling and heating air conditioning system provided by the invention can supply cooling and heating at the same time, so as to meet the needs of use in different seasons. The specific implementation is as follows:
[0055] In summer, the cooling source in the floor radiant coil can provide cold water for chillers, etc., the supply and return water temperature is 18°C / 21°C, and the cold water and the floor heating pipe wall conduct heat transfer through heat conduction and convection heat exchange; According to the design standard, the indoor air temperature in summer is generally 25~27℃, and the relative humidity is 55%~65%.
[0056] In winter, the heat source in the floor radiant coil is an electric boiler, the supply and return water temperature is 35°C / 25°C, and the heat transfer method is the same as in summer.
[0057] like figure 1 As shown, the present invention provides a buried floor radiant cooling and heating air-conditioning syste...
Embodiment 2
[0070] The embodiment of the present invention provides a control method for a buried floor radiant cooling and heating air-conditioning system as follows:
[0071] Step 1: each room is monitored by the central processing unit 15, and the employees feed back the number of people in each room to the central processing unit 15 by punching in at work;
[0072] Step 2: each room temperature and humidity sensor 16 monitors each room in real time, and transmits the data to the central processing unit 15;
[0073] Step 3: The central processing unit 15 performs intelligent analysis and processing on the collected temperature and humidity data and the number of employees, and calculates the design load required by each room.
[0074] Step 4: According to the design load required by each room, the central processing unit 15 issues an instruction to precisely regulate the latent heat load and temperature and humidity required by each room by regulating the frequency of the air-condition...

Abstract
The invention belongs to the technical field of floor radiation air conditioners, and discloses a buried structure type floor radiation cooling and heating air conditioning system and a regulation and control method. The regulation and control method of the buried structure type floor radiation cooling and heating air conditioning system comprises the steps that indoor sensible heat is eliminated through the independent low-temperature water system and the cold radiation plate in a radiation and convection mode; and the sensible heat which is not eliminated is eliminated by introducing the dehumidified outdoor fresh air, and all latent heat loads are carried out, so that the surface of the cold radiation plate is prevented from being dewed. Air-conditioning water is adopted for cold storage and heat storage, trough electricity is utilized for energy storage, in the embodiment of a certain industrial park of Qingdao, statistical data in 2020 shows that the annual actual peak load shifting electricity consumption of the park is 8587000 kWh, and compared with traditional air-conditioning refrigeration and municipal central heating, carbon emission is correspondingly reduced by 7385.16 tons. The buried structure type floor radiant cooling and heating air conditioning system can realize cooling in winter and heating in summer, solves the problem of surface condensation during floor radiant cooling, and does not have a blowing feeling.
Description
technical field [0001] The invention belongs to the technical field of floor radiant air conditioners, and in particular designs a buried-structure radiant floor radiant cooling and heating air conditioning system and a control method. Background technique [0002] Radiant floor air conditioners are widely used in residential, office and other civil buildings. In order to prevent condensation on the floor surface, conventional floor radiant coils mostly use ordinary high-temperature hot water as the medium, which can only meet the heating demand; conventional air-conditioning systems mostly have obvious blower In addition, the radiant floor air conditioner is mostly adjusted by the central control system, which cannot meet the different needs of people in all rooms for cold and heat, which restricts the popularization and development of radiant floor air conditioners. [0003] Through the above analysis, the existing problems and defects in the prior art are: [0004] (1) T...
